StableEmail Delete Subdomain Inbox

Use this endpoint when you need to permanently remove a specific email inbox (localPart) from a StableEmail-managed subdomain. Prefer this over the single-message delete endpoint when you want to remove the entire inbox rather than individual messages. Ideal for cleanup workflows, deprovisioning user accounts, or retiring unused forwarding addresses on a custom subdomain.

• Inbox or subdomain not found — returns error if the localPart or subdomain does not exist
• Invalid localPart format — localPart must match pattern ^[a-z0-9][a-z0-9._+-]{0,62}[a-z0-9]$
• Invalid subdomain format — subdomain must be lowercase alphanumeric with hyphens, no consecutive hyphens
• Inbox already deleted — attempting to delete a non-existent inbox may return an error
• Unauthorized deletion — if the subdomain is not owned or verified by the caller
